    • PURPOSE:To obtain periodic multi-layered films which satisfy the requirement as a spacer by laminating alternately an Si oxide having a specified film thickness and a metallic oxide. CONSTITUTION:The oxide of Co, Ni, Fe and other metal and the oxide of Si are alternately deposited by evaporation to a specified film thickness on a substrate to form periodic multi-layered films. The substrate 1 placed in the upper part in a vacuum vessel 1 for the above-mentioned purpose is heated to a suitable temp. by a heater 2 and while oxygen is introduced into the vessel through a gas introducing port 5, SiO and metals such as Co, etc. in vapor sources 31, 32 are alternately evaporated in an oxygen atmosphere kept under 4X10 Torr. The periodic multi-layered films satisfying the conditions as a spacer are thus obtd.
    • 目的:通过交替层叠具有特定膜厚度的Si氧化物和金属氧化物来获得满足作为间隔物要求的周期性多层膜。 构成:通过蒸发将Co,Ni,Fe等金属的氧化物和Si的氧化物交替地沉积在基板上以规定的膜厚度形成周期性的多层膜。 将用于上述目的的放置在真空容器1中的上部的基板1加热到合适的温度。 通过加热器2,并且当通过气体导入口5将氧气引入容器中时,蒸气源31,32中的SiO和诸如Co等的金属在保持在4×10 -4 Torr的氧气氛中交替蒸发。 因此,满足作为间隔物的条件的周期性多层膜。
